| 摘要 |
An asymmetric semipermeable membrane and processes for the manufacture thereof are disclosed. The membrane comprises at least one hydrophobic polymer and at least one copolymer based on acrylonitrile, at least one sulphonic monomer which is optionally salified, and optionally at least one non-ionic, ionizable, olefinically unsaturated monomer. The membrane is useful in the treatment of biological fluids such as plasma or blood, especially using plasmapheresis, or with the aid of an artificial kidney using hemodialysis and/or ultrafiltration. |
